Components: a) Mono cassete player- you can get it for $5 at a yard sale. b) a 1/4″ jack and some wire.

Assembly procedure:

De-solder the playback head and solder the 1/4″ jack to the two wires.

Playing Instructions:

Plug into the 1/4″ jack and press ..well.. PLAY! (duh) Turn up the volume to full.

Evaluation notes:

The sound is very compressed and distorted with super long sustain and squealing feeedback(especially with a rickenbaker) Works best with a humbucker. You can almost get a clean tone if you turn down the volume on your guitar. I used a minimus7 speaker with it and got suprising results on tape!

A guy I know built one of these years ago and once I heard it had to make on for myself(this is a great Xmas gift for someone who needs an amplifier).

On mine I started removing things like the motor etc and finally just said screw it and installed the circuit board and speaker into an empty Kraft Dinner Box.
